  1. Lithium is a chemical element with atomic number 3 which means there are 3 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.

  6. 20 mar 2023 · The total number of electrons in a valence shell is called valence electrons. The electron configuration shows that the last shell of lithium has only an electron. Therefore, the valence electrons of lithium are one.

  7. 22 sie 2024 · The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a lithium atom has three protons and three electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons.
